Problem 64P
A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 14.0 s. It runs at constant speed for 70.0 s and slows down at a rate of 3.50 m/s2 until it stops at the next station. Find the total distance covered.
ANSWER:
Solution 64P
u= 0( it starts from rest)
t= 0 to 14 s
a=1.6 m/
To find the x-
Consider the train is travelling in positive x direction
We have formula
a= acceleration along x axis
u =initial velocity along x axis
v= final velocity
x- =ut+a
